The goal of the M600-B was to be the ultimate EDC carry light, it had to be able to meet the highest demands possible. It was designed around the best components available. With the ever advancing LED options the M600-B uses the versatile P60 style modules. The P60 has the potential to put out 800 lumen OTF (Out The Front) on high or about 80 lumen (10% power) OTF (Out The Front) on low. The M600-B is paired with Nailbender’s Customlites, which are some of the best P60 engines in the industry. This light features a McGizmo McClicky and an 18650 LiOn battery. Adding the best components wasn’t enough. The machine work on this light has to be up to American machined quality. With all the choices in the P60 style engines the light housing is capable of changing out light engines easily and quickly. The M600-B has a known presence in your hand, it is not heavy but you can feel the quality of this light when the need arises for it to shine.
